I'm using a 3d ProphetDDR with a 600athlon and a K7M motherboard. I recently installed the new Detanator3 drivers and ever since I've been getting Rundll32 errors whenever accessing the card with things like going to settings to change my res or accessing any games. For some reason after I get the error a couple times it will work(sometimes). So usually if I access the app a couple times I can get it to run ok, but recently it hasn't been going away at all. I don't think it's heat problems and I've tryed downgrading the drivers but nothing seems to work. I've heard of problems with geforce/athlon processors but I thought that was just with 700/750(Irongate) processors.
